Hide fields on embedded form

Hide fields on embedded form

Hi I have created a form which is being embedded in my site for people to fill in. I have 3 fields on the form which I don't want them to see, as they will be completed afterwards by myself.

I chose "hide this field to others" when adding the fields, but they still show up on the embedded form.

Is there anyway to hide them on the embedded form so that when I login I can then update them?

many thanks
